The 2016 Goat Rodeo contenders have less than 2 weeks to generate enough buzz that they can get one of the ten Wonka-like tickets to participate on the first debate on Fox News. The way they create buzz is to create a ruckus. They create a ruckus on Fox News by calling each other names.
Obvious Anagram Reince Priebus doesn’t seem to realize that the candidates’ name calling is the natural result of what would happen once he punted all the decisions about debate rules/regulations/participation to Fox News.
“Greater” Wingnuttia likes their candidates to be bellicose, belligerent, and bombastic. They don’t want a reasoned argument with factual data points, they want the guy who shouts the loudest and throws the pie with the most accuracy, and who supports whatever is their grievance of the day (the Kenyan Usurper).
